SOC 2 (short for Service Organization Control 2) is an auditing standard developed by the AICPA (American Institute of Certified Public Accountants) to assess the level of internal control of service providers, especially those providing services related to information technology and cloud computing. Successfully building and implementing an SOC 2 system is considered a successful first step in ensuring systematic data security. In this article, SQC Certification shares with you the steps to building and implementing the SOC 2 standard in the most systematic way.

What is SOC 2 compliance?
SOC 2 (short for Service Organization Control 2) is an auditing standard developed by the AICPA (American Institute of Certified Public Accountants) to assess the level of internal control of organizations providing services, particularly those related to information technology and cloud computing. The SOC2 standard includes five principles for evaluating the reliability of customer data management services. The goal of SOC2 is to ensure that data management service providers secure both the company’s own information and that of its customers.
The SOC 2 standard provides a framework for security and auditing to verify whether your company or organization complies with SOC 2 requirements. SOC 2 defines the requirements for managing and storing customer data based on five Trusted Service Criteria (TSCs):
- Protection
- Availability
- Processing Integrity
- Security
- Privacy
Steps to build and implement the SOC 2 standard
STEP 1: Define the Scope
Your organization or business needs to clearly define the scope of its services that will be covered by SOC 2. Unlike other ISO standards, SOC 2 does not necessarily have to cover the entire organization; it can be a specific system or service.
Defining the scope can help your organization choose the appropriate type of report. Currently, the SOC 2 standard has two types of reports:
- Type I – evaluation of control design at a single point in time
- Type II – evaluation of design and operational effectiveness over 3–6 months

STEP 2: Risk Analysis & Selection of Principles
Your organization or business needs to analyze risks and select appropriate principles to apply. Typically, organizations today apply the five TSC principles, including:
- Security (mandatory)
- Availability
- Processing Integrity
- Confidentiality
- Privacy
A thorough risk analysis and identification of appropriate control measures for each principle are crucial for optimal application.
STEP 3: Designing the Internal Control System
Your organization needs to plan and design a truly successful internal control system. This includes establishing policies and procedures, as well as selecting the most appropriate tools. Some internal control tools include: access management, system monitoring, logging, backup and recovery, incident response, employee training, and data access control.
Fully documenting policies: security policy, access control policy, incident response plan, etc.
STEP 4: Implementation & Audit Evidence Collection
At this step, your organization implements measures to control and ensure evidence is recorded, such as access logs, backup reports, incident handling reports, access control tables, etc.
For organizations using SOC 2 Type 2, a monitoring assessment should be conducted every 3-6 months to ensure the system operates most effectively.
STEP 5: Third-Party Audit (CPA Firm)
Your organization needs to select an accredited assessment organization to evaluate the systems your business has implemented.
STEP 6: Receive the Official SOC 2 Report
Organizations that meet the requirements will be issued a SOC 2 Report. With this report, your organization can share it with clients and partners to effectively demonstrate its security and compliance capabilities.

STEP 7: Maintain and Improve the Control System
For SOC 2 Type 2 reports, periodic monitoring and evaluation are required annually. Organizations need to continuously update processes, train staff, and apply security technologies to ensure the system always meets requirements.
SOC 2 Implementation Timeline
- Internal preparation & system design: 2–4 months
- Evidence gathering phase (Type II): 3–6 months
- Auditing and reporting: 1–2 months
